SPRAYING- MACHINE,

Application filed. August 7, 1924. Serial No. 730,762.

1 '0 all whom it may concern:v

Be it known that I, E MILTON Hon'ron, a citizen of the United States, residingiat Albion, county of Calhoun, State of Michigan, have invented certain new and useful Improvements in Spraying Machines, of which the following is a specification.

This invention relates to improvements in spraying machines.

My improved spraying machine is especially designed by me for greasing bakers pans, although it is desirable and readily adapted for use in other relations, as for washing or sterilizing pans and the like.

The main object of this invention is .to-

provide an improved spraying head which is well adapted for handling liquids such as hot grease, is not likely to become clogged, or should it become clogged can be readily cleaned without disassembling.

A further object is to provide a machine of the class described which is readily adjusted for different kinds of work.

Objects pertaining to details and economies of my invention will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.' The inventionfis clearly defined and pointed out inthe claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this application, in which:

1 Fig. I is a fragmentary view of a spray ing machine embodying the features of my invention as I have adapted the same'for pan greasing machines, a spray head being shown in vertical section on line corresponding to line 1-1 of Fig. II.

The sectional views are taken looking in.

the directionof the little arrows at the ends of the section lines and similar numerals of reference refer to similar parts throughout all of the views.

Referring to the drawing, 1 represents a opens.

opening to the annular connected through details of the machine, as adapted way or track along which the articles to be sprayed, as the bakers pans 2, may be pushed. A series of pans is shown in the accompanying drawing connected by the straps 3 as is the usual practice;

The spray heads designated generally by the numeral 4- are adjustably supported by the rod '5 to discharge into the inverted pans.

6 re aresents the rease van for lard or other material.

My improved spray heads comprise the outer or body members? having cylindrical chambers 8 therein terminating atthe upper end in a conically tapered throat 9-wl1ich' opens into the countersunk tip 10. The inner member 11 has a threaded portion 12 at its lower end threaded intothe lower-end of the chamber 8,'a'cylindrical portion 18 and a conical portion 1a fittingwithinthe chamber 8; I

Between the cylindrical portion and the threaded "portion the inner member has a reduced portion 15 providing an annular air passage 16 into which the air conduit .17 The conical portion of theinner member projects through the throat of the outer member and terminates in an outwardly flaring heador tip 18 which is supported in spaced 10, the cylindrical portion. of the inner mem'v her having longitudinal grooves 19 therein providing, discharge passages, these aassages passage 16. The inrelation tothe countersink I nor member has a longitudinal liquid pasl sage 20 with the branches 21' opening to the discharge passages. i

The passage 20,.

the pipe 22 which extends into the grease'pan 6. With the parts thus arranged, the air being suppliedthrough Fig. II is a fragmentary plan view showthe pipe 17, is discharged through the discharge passages, carrying the liquid with it with an atomizer effect. This is discharged upwardly against the deflecting tip 18 and is effectively sprayed out between this tip and the countersink 10. r

The conduits 17 are provided with flexible, portions connected to the" air supply of the inner memberis pipe 23 through the valves 24. The-liquid supply pipe 22 is providedwith a screen 25 and has a notch-like opening 22- in spaced relation to its lower end so that whenthe liquid in'the tank or pan 6 falls below a predetermined point, the device becomes innozzles, and it would be objectionable to discharge such material into the pans. However, should the nozzle become clogged, to

clean it effectively, it is only necessary to place the hand or a pad over the discharge of the nozzle. The air then passes from the discharge through the passages 21 and 25 and the pipe 22-, freeing the same from any obstructions.

To readily adapt the machine to diil eront sized pans the spray heads are adjustably supported on the rod 5, the outer or body members of the heads being provided with clamp arms 26 and 8 adapted to receive the red as shown in l. A boit engages the clamping wedge 2-30 disposed in the opening 31 oi? the arm 28 so that by turning the nut the clamping wedge is drawn against the rod. This provides in ans where- AAA by the spray heads may be adjusted to the desired position and a very decided advantage as it will be understood that most bakeries use pans of different sizes.

I have illustrated and described my invention in an embodiment which I have found very practical. I have not attempted to illustrate or describe certain embodiments and adaptations which it contemplate as i believe the disclosure made will enable those skilled in the art to which this invention relates to embody or adapt the same as may be desired.

ll clann as new and desire to secure by tors Patent, is:

1. In a spray nozzle, the combination of an outer member having a cylindrical chani ber therein terminating at one end in a conically tapered throat opening to a countersunk tip, an inner member threaded into the bottom of said chamber and having a lon 'itudinail grooved c lindrical chamber providing discharge passages, said chamber having a air connection opening to said passages, said inner member having a longitudinal liquid passage with discharge orifices aligned with said grooves.

In a spray nozzle, the combination of an outer member having a cylindrical chamber therein terminating at one end in a coni cally tapered throat opening to a countersunk tip, an inner member having a longitudinally grooved cylindrical portion, and a conical portion projecting through said throat and terminating in a daring tip snaced from the countersunk'tip of said outer member, said grooves coacting with the walls of the chan'iber providing discharge passages, said chamberfhaving an air coamection opening to said passages said inner member having a liquid passage opening to said discharge passages.

3. In an apparatus of the class described,

the combination of an air supply pipe, aplurality of spra nozzles having clamp members at one s1 Le thereof, a supporting rod with whichsaid clamp members are engaged, whereby the nozzles may be adjusted thereon, flexible conduits connecting said nozzles with said air, pipe, a liquid supply tank, and liquid conduits for said spray nozzles depending into said tank.

In witness whereof,

I have hereunto set my hand. i
